Four capybara newborns, members of the world’s largest rodent species, underwent their first veterinary examinations Wednesdday at the San Diego Zoo.
The capybaras weighed between 3 1/2 and 4 pounds when born in the Harry and Grace Steele Elephant Odyssey exhibit, where they were discovered by keepers around 6 a.m. Monday.
It’s the sixth litter for their mother, Buttercup, who has given birth to a total of 23 babies. The father of her latest brood is a capybara named Wesley.
The exam included weighing the youngsters; checking their eyes, ears and overall physical health; and taking a sample of hair for use in determining their sex.
Like many other species of rodents, there are no visible signs to indicate the sex of the animals until they reach maturity, which is about 18 months to two years.
The capybaras, which are walking and swimming on their own, are already on display for zoo visitors. All of the females in the group help to care for and even nurse the babies.
Capybaras are found east of the Andes Mountains, on Central and South American riverbanks, beside ponds and in marshes, or wherever standing water is available.
Due to its dry skin, the capybara requires a swimming hole to stay healthy.
While capybaras are not classified as an endangered species, they are threatened by deforestation, habitat destruction and illegal poaching. People who live in capybara habitats have used the rodent as a food source for centuries, and have been seen wearing their teeth as ornaments.
